Abstract
Various complex salts and sulfonic acid salts of tetradiazo copper phthalocyanine were synthesized and their decomposition behaviors studied. They served as polymerization initiators for vinyl type monomers more effectively than simple diazonium salts. Azo-type as well as polycyclic-type polymeric coloring agents were thus prepared using the complex salts stabilized with zinc chloride. The crystalline structures of the colors so obtained remain unchanged in a solvent. They were in the forms of ultrafine dispersion, and the resin and the chromogen moieties could not be separated by fractional precipitation or extraction. The products obtained in the present study were probably of higher molecular weight than the ones obtained using a simple diazonium salt as judged by their high intrinsic viscosities.
